Serial No. 252,171.

To all whom it may concern:

Be it known that I, GEORGE O. FERGUSON, a citizen of the United States,residing in the city and county of Denver and State of Colorado, haveinvented certain new and useful Improvements in Inhalers; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

My invention relates to improvements in inhalers, my object being toprovide a device of this character which shall be of novel constructionand adapted to be carried in the pocket of the user whereby it isreadily accessible at all times.

The device consists of a casing adapted to hold a container consistingpreferably of wire gauze mesh in which is placed a quantity of absorbentmaterial as cotton adapted to hold a suitable substance sufficientlyVolatile for inhaling purposes.

The instrument when in use is open at both ends, the air laden with thevapor to be inhaled escaping into the nostril of the user at oneextremity, while the air enters the instrument at the oppositeextremity. When not in use both extremities of the device are closed,practically air tight for obvious reasons.

Having briefly outlined my improved construction as well as'the functionit is intended to perform, I will proceed to describe the same in detailreference being made to the accompanying drawing in which is illustratedan embodiment thereof.

In this drawing, Figure 1 is a longitudinal section taken through myimproved device complete and shown in the closed position. Fig. 2illustrates the device with beth extremities open, or in position foruse. Fig. 3 Shows the device with one section of the casing removedpreparatory to taking out the gauze tube for recharging it with thevolatile substance to be inhaled. Fig. 4 is a detail view of the gauzetube or container. Fig. 5 is a sectional view of the container partlybroken away and shown on a larger scale.

The same reference characters indicate the same parts in all the Views.

Let the numeral 5 designate a casing which is preferably cylindrical inshape. One extremity of this casing is provided with a threaded orifice6 adapted to receive a screw 7. The opposite extremity of the body ofthe casing consists of a section 8 threaded upon the main member 9'asshown at 10. This member 8 is reduced in size as shown at 13 andprovided with an escape orifice 12. This reduced extremity is adapted toenter the nostril of the user during the inhaling act. The extremity 13of the device is concealed by a cap 14 threaded thereon as shown at 15.

Vithin the body of the tube 5 is located a cylindrical container 16which as shown in the drawing is composed of two ferrules or rings 17and 18 connected by mesh material 19 preferably composed of wire gauze.This container is open at both ends and in it is placed a suitablequantity of absorbent material 20 adapted to hold the volatile substancewhich is tobe inhaled.

From the foregoing description the use and operation of my improveddevice will be readily understood.

The container 16 ts loosely within the body of the device whereby theair within the casing is adapted to circulate freely therearound as wellas through the meshes thereof.

As heretofore intimated when the device is not in use it may be carriedin the pocket of the user, the parts in that event being assembled asshown in Fig. 1. When itis desired to use the device, the cap 14Ctogether with the screw 7 are removed. The reduced extremity 13 is theninserted in one of the nostrils and during theinspiration of thepatient, the volatile substance passes into the nostril, from the exitend of the instrument simultaneously with the entrance of air at theopposite or inlet end thereof. Vhen it is desired to remove thecontainer for the purpose of recharging the same with the volatilematerial, the section 8 of the device is removed as shown in Fig. 3. The

container may then be withdrawn from the tube7 recharged and replaced.

In addition to the use of the instrument heretofore explained, forinhaling the volatile substance by inserting the extremity 13 in thenostril, the throat may be treated preferably by employing the oppositeextremity of the instrument after its screw plug 7 has been removed anddrawing the volatile substance into the throat through the saidextremity, the cap 14 being re= moved to allow the air to enter the tubethrough the opposite extremity. The screw plug extremity of theinstrument is better adapted for treating the throat since it is roundedand smooth thus leaving no rough surface which might cause or tend toCause irritation. o

Having thus described my invention, what I claim is: A

An inhaler comprising a tube composed of two members, a main member andan auxiliary member, the main'nember having a relatively small threadedorifice at 'one extremity, a Vs'orei'v plug threaded therein, the Saidthreaded extremity being adapted to be inserted in the mouth, theauxiliary member having a reduced oriieed extremity adapted to enter thenostril, the two members being detacliably connected, and a containercomposed of two rings connected by Wire gauze, the container beingloosely arranged Within the tube and containing absorbent materialadapted to be saturated with a volatile substance, the container beingentirely open at both extremities, the openings in both extremities ofthe tube being too small to permit the escape of the Container.

In testimony whereof I my signature in presence of two Witnesses.

GEORGE O. FERGUSON.
